Magnetic Particle Testing (MT)
Magnetic Particle Testing (MT) is a widely used non-destructive testing (NDT) method for detecting surface and near-surface discontinuities in ferromagnetic materials such as steel, iron, and nickel. It is highly effective for identifying cracks, laps, seams, and other discontinuities that may not be visible to the naked eye.
Del NDT Services
At Del NDT Services, we use advanced magnetic particle inspection techniques — both wet and dry methods, using fluorescent or visible particles — to ensure precise and reliable detection of surface defects. When a magnetic field is applied to a component, any discontinuity on or near the surface causes a leakage field, attracting the magnetic particles and forming a visible indication of the flaw.
- Detects fine surface and slightly subsurface cracks with high sensitivity
- Fast, cost-effective, and ideal for on-site inspections
- Suitable for complex shapes and welds
- Immediate results with minimal surface preparation
Applications
All MT inspections at Del NDT Services are performed by certified technicians in accordance with Australian and international standards (AS 1171, ASTM E709, ISO 9934) to ensure accuracy, safety, and compliance with client specifications.
- Weld inspection and quality assurance
- Structural steel and fabrication components
- Pressure vessels and pipelines
- Automotive, mining, and manufacturing equipment
